Abstract

(57) [Summary] The present invention provides a method and system for referencing, recording, and retrieving symbolically linked information despite the use of unique symbols (120a1, 120c1, 120a2, 120c2, 120a3, 120c3). I will provide a. The master 115c database stores a plurality of master symbols 115c, each formatted according to a predetermined structure. Each master symbol 115c in the master symbol 115c database is linked to a parent identifier 110 that identifies a unique object 130. The user can archive or retrieve symbolically linked information in the information database by providing input symbols. The input symbols are normalized and the master symbol 115c database is searched for a matching master 115c. The parent identifier 110 linked to the matching master 115c is then used to retrieve or archive information in the information database.

Detailed Description of the Invention

FIELD OF THE INVENTION The present invention relates to electronic storage and retrieval of information. In particular, the present invention
How to browse, store, and retrieve information linked to a brick
Concerned. [Background information] Many types of information are referenced in daily life using symbol codes.
It is archived. Typically, the symbol code is a code
A specific set of asserted objects in the real world represented by a symbol
Used by a group of users that require a consistent and convenient language for referencing entities.
Used. However, in reality, most symbol codes are not stylized.
User and therefore uses these codes harmoniously and consistently.
Absent. Therefore, it is difficult to interpret the symbol. For example, in the financial world, financial transactions refer to companies and their securities.
Each uses a different set of transaction (ticket) symbols. Although in the United States,
Scalars harmonize symbol names, and in general, global deals
A specific symbol set and symbol structure is used to identify those securities.
For example, PSE (Pacific Stock Trading) and NYSE (New York Stock)
Both exchanges use the symbol "IBM" to represent IBM securities.
However, in the United States, the symbol “T” refers to AT & T securities, while
In Da, "T" refers to the securities of the company Telos. In the UK, the symbol "T" is
Can refer to corporate securities. Financial information vendors such as Reuters, Bloomberg, Bridge, etc.
It also uses a unique set of symbols and structures to refer to companies and their securities.
To use. Many financial information vendors are separated by a delimiting character.
A structural symbol code segmented into two separated parts is used. For example
, Vendors refer to securities of certain companies whose ROOT segment
A symbolic ROO whose segment refers to the country or exchange in which the security is traded
T (character that defines the boundary) SOURCE can be used. Set boundaries
The character that is used is typically "@" or ".". There are a number of symbol sets in circulation that identify the securities and companies to which they belong.
Because of this it is difficult to interpret the symbol. For example, a single vendor
Refer to the IBM securities traded in Lance and use the symbol "IBM.FR"
Used to refer to the same IBM securities traded in the UK and use the symbol "IBM.
GB "can be used. In both cases, the symbol IBM. FR and
And IBM. Both GBs relate to the same corporate IBM. However, the two
To refer to two different securities issued by two different companies.
You can use the same root and source segments. For example, the first Ben
Dar refers to AT & T securities traded in the United States and assigns the symbol "T.US"
Could be used, while the second vendor would have to trade the securities of different companies for reference.
The label "T @ US" can be used. On the other hand, two different vendors
Use different root and source symbols to refer to the same security
Yes, the first vendor could refer to IBM's securities traded in the UK
, The symbol “IBM.UK” can be used, while the second vendor has the same I
Use the symbol "IB.EG" to refer to the same IBM securities, referring to BM securities
You can The need for a consistent system to reference financial information linked to a particular company
Is becoming increasingly important as online financial research grows.

Indicates a sub-object of. At the bottom of FIG. 1, an example object 130 and
, Sub-objects 140a-140b related to the object 130.
Also shown in FIG. 1 is an object space 15 consisting of all possible objects.
Indicates 0. For example, according to one embodiment, object space 150 is
Object 130 represents a particular company, including all companies traded in it.
I, the associated sub-objects (eg 140a-140c), depend on the company.
Represents the securities issued by. At the top of FIG. 1, an object 130 and sub-objects 140a-140c are shown.
2 shows the structure of a master symbol database representing. In particular, the parent identifier 110 is
In relation to the object 130, the master symbols 115a to 115c are sub-objects.
Related to each of the objects 140a-140c. The top and bottom of Figure 1a are
It is almost symmetrical. As shown in FIG. 1a, each master symbol has (for example, 115
a-115c) are linked to the parent identifier. Each parent identifier 110 is sequentially
It is related to the only object that exists in the eject space 150. The function of the master symbol database is to determine the specific objects based on the input symbols.
It is to be able to identify This is 3 flats of object space 150
Shown by the intersection of faces. The input symbol is positive, as described in detail below.
A standardized master symbol database will find matching master symbols.
Be searched for. The parent identifier linked to the matching master symbol is
It is used to identify the object 130. Figure 1 shows only one parent identifier and three master symbols
The database typically contains many master symbols, of which each mass
The ta symbol is linked to one of many parent symbols 110. For example, Figure 1b
Master symbols 115a-115c are linked to the parent identifier 110a,
Symbol 115d to 115f are linked to the parent identifier 110b, and the master symbol
115 g to 115 k are linked to the parent identifier 110 c, and the master symbol 115
1-115 m are linked to the parent identifier 110 d. Like this, Master Shin
Vols 115a-115c relate to the first object and are associated with the master symbol 115.
d to 115f relate to the second object, and master symbols 115g to 115
k is related to the third object, and the master symbols 1151 to 115m are the fourth objects.
Related to objects. A further example illustrates the application of the scheme shown in Fig. Ia. Book
According to the invention, each object 130 represents a company and each sub-object (
For example, 140a to 140c) represent securities issued by the company. this
By way of example, a unique parent identifier 110 is assigned to each company. By a specific company
Each security issued is assigned to a unique master symbol.
The star symbol is the parent identifier 110 assigned to the company issuing the securities.
Linked to. Each master symbol has a mass with a linked parent identifier 110.
It is stored in the symbol database. According to one embodiment, all masters stored in the master symbol database
The symbol utilizes a predetermined structure defined by the symbol template.
FIG. 1c shows a symbol template according to an embodiment of the present invention. Symbol ten

Represents a particular attribute of the symbolized object or sub-object.
Correspond. In this way, according to the same predetermined symbol template 145
All master symbols are stored in the assembled master symbol database.
Be done. In particular, each master symbol stored in the master symbol database is a symbol
Of each symbol field 150 (1) defined by the rule template 145.
A master symbol segment is included corresponding to 150 (N). Each symbol segment
The text contains a text string. For example, in the symbol field related to country attributes
In contrast, the symbols stored in the master symbol database are
Symbol segment (ie text string) "US", which belongs to each country,
It may include “GB” and “FR”. For example, Figure 1a shows three symbol fields.
A mass assembled according to the symbol template 145, including a code (not shown).
